How to send floating point values over radio in TinyOS

Please do forgive me if this is a very primitive question.

What data type I need to send a floating point value such as "27.654" over radio? I mean do I need nx_uint32_t or something else?

I am asking this because I want to send exact temperature to BaseStation.

Thanks,
Sean.

CC430f5137 UART Issue on TinyOS

Hi,
 
I have a CC430f5137 based custom mote on which I've been able to compile the Blink example, by setting the SURF platform as REV A (I'm using Tinyprod). For Blink to work I had to change the LED pins, as the LEDs on the SURF REV A board are connected to P1.0, P1.1, P1.2, P3.6 and 3.7.
I changed these to match my mote (my mote has LEDs connected to P1.7, P3.6 and P3.7) in the PlatformLedP.nc file (in tos/platforms/surf/hardware/leds) as follows:
 
#elif defined(SURF_REV_A)
    //{ (port_t*)P1IN_, 1 << 0 }, // Blue
    //{ (port_t*)P1IN_, 1 << 1 }, // White
    { (port_t*)P1IN_, 1 << 7 }, // Red on my mote
    { (port_t*)P3IN_, 1 << 6 }, // Green on my mote
    { (port_t*)P3IN_, 1 << 7 }, // Orange on my mote
 
Now I'm trying to get UART working but my FTDI cable's RX and TX pins are connected to pins P2.0 and P2.1, respectively, and not to the default P1.5 and P1.6 pins. Hence, I made the following changes to the PlatformsPinsP.nc file (in tos/platforms/surf/hardware/pins) to reflect this difference:
 
//#if 0 /* Disabled:These specific setting sare defaults, but others might not be */
#if defined(SURF_REV_A)
    PMAPPWD = PMAPPW;                         // Get write-access to port mapping regs 
    //P1MAP5 = PM_UCA0RXD;                      // Map UCA0RXD output to P1.5
    //P1MAP6 = PM_UCA0TXD;                      // Map UCA0TXD output to P1.6
    P2MAP0 = PM_UCA0RXD;                    // Map UCA0RXD output to P2.0
    P2MAP1 = PM_UCA0TXD;                    // Map UCA0TXD output to P2.1
    PMAPPWD = 0;                              // Lock port mapping registers
#endif
 
These two are the only files I've changed.
Flashing the TestSerial app to my mote does not produce any output when "java net.tinyos.tools.Listen -comm serial <at> /dev/ttyUSB0:115200" is run. It hangs at "serial <at> /dev/ttyUSB0:115200: resynchronising" and nothing happens.
If I use Putty with TestSerial running on my mote, I can see a sequence of bytes being periodically displayed on Putty (they are unreadable, which is expected) so I'm assuming the serial connection is fine.

I tested the SerialTest app on a TelosB mote and "java net.tinyos.tools.Listen -comm serial <at> /dev/ttyUSB0:115200" works 100%, so I'm assuming my Java config is correct.
 
And I know the serial connection is working 100% OUTSIDE TinyOS as I have tested it with a UART CC430f5137 sample 
C code from TI, by using:

P2MAP1 = PM_UCA0TXD;         // Map UCA0TXD output to P2.1
P2DIR |= BIT1;                          // Set P2.1 as TX output
P2SEL |= BIT1;                         // Select P2.1 UART function
 
Any ideas as to what is causing this issue?
Thanks!
 
Regards
Jorge

Re: How to disable Crc in IRIS Nodes

Hi Stephen,

Look at RF230DriverLayerP.nc, there you will find the check for
correct CRC in the receive path. I think the best would be to use a
specially formatted message and in RF230DriverLayerP you manually copy
the CRC correct/incorrect bit to a known location to the message and
let the message processing through. However, if the bit corruption is
somewhere in the header, then the radio stack might not signal the
message correctly to the upper layers (it might fire for a different
AM receiver). If you want complete control, the you have to write and
wire up everything by yourself. Take a look at the
apps/test/rfxlink/sniffer application how to use the driver layer
directly without all the other upper stuff.

Best,
Miklos

MicaZ current measurement for different Transmission Power settings

Dear all,
I want to measure the current consumption of MicaZ when Transmission Power is set to different values like 0dBm, -3dBm, ... -25dBm and compare my measurements with data sheet of MicaZ.
for this aim I prepared a code. In this code the transmitter mode is activated and receiver mode is deactivated. There is no sensor board on the mote and all of the LEDs are turned off. and Micaz is broadcasting its node ID.
The code is working fine for different  Transmission Power settings. it means that when I set the Output Power to various mode the data is receivable at different distance.

My question :
for different Transmission Power settings the measured current is about 22.9mA when sending packet and 22mA when not sending data. but according to datasheet for different Transmission Power settings we should have different current consumption.
could you please help to find out the problem?


With Best Regards,

CfP: Int. Workshop on Real-world Wireless Sensor Networks - Submission approaching!

Call for Papers: The Fifth Workshop on Real-World Wireless Sensor Networks
==========================================================================

                        19-20 September 2013
                         Como Lake (Italy)
                 Follow REALWSN on Twitter: <at> RealWSN! 

We are excited to announce that the fifth Workshop on Real-World
Wireless Sensor will be held at the Como Lake, Italy in September 2013.

The purpose of the fifth Workshop on Real-World Wireless Sensor
Networks (REALWSN) is to bring together researchers and practitioners
working in the area of sensor networks, with focus on real-world
experiments or deployments. Included are, nontheless, new forms
of sensing such as those that leverage smart phones, Internet of
Things, RFIDs, and robots.

When working with real-world experiments or deployments, many new
issues arise: the network environment may be composed of a variety of
different technologies, leading to very heterogeneous network
structures; software development for large scale networks poses new
types of problems; prototype networks may differ significantly from
the deployed system; actual sensor network deployments may need a
complex combination of autonomous and manual
configuration. Furthermore, results obtained through simulation are
typically not directly applicable to operational networks and it is
therefore imperative for the community to produce results from
experimental research.

Authors are invited to submit papers (12 pages, Springer format, 10
point font size) for presentation at the workshop. Papers will be
selected based on originality, technical merit, and
relevance. Submissions must be fully anonimized, as REALWSN will apply
a double-blind review process. Accepted papers will be published by
Springer in the Lecture Notes on Electrical Engineering series and
indexed by all major digital libraries (e.g., ISI, Scopus, Google
Scholar, ...).

All topics pertaining to real-world wireless sensor networks and modern 
forms of sensing are of interest, including but not limited to:
    * Experiences with real-world deployments
    * Mining real-world sensor network data
    * Sensor systems leveraging smart phones (crowd sensing) 
    * Sensors systems involving Internet of Things (IoT), RFIDs, robots 
    * Experimental validation/refutation of previous simulation
      results obtained by others
    * Real-world performance of self-organization and self-management
    * Debugging, testing, validation, and management
    * Deployment and configuration
    * Applications in medicine, industry, science, environmental monitoring
    * Security and trust
    * Scalability in practice
    * Development and prototyping platforms
    * Operating systems, sensor network programming paradigms, and languages
    * Middleware for heterogeneous networks
    * Real-time and dependability issues
    * Hardware support for real-world sensor networks
    * Robustness at all levels: communication, software, hardware
    * Energy efficient protocols
    * Hardware and software methods for energy measurement and profiling
   
Important dates:
    * Electronic submissions due: June 21st, 2013
    * Notification of acceptance: August 8th, 2013
    * Camera-ready copy due: August 30th, 2013

RSSI readings on the Tinynode584 / XE1205

Hi,
 
I have several tinynode 584 modules which use the XE1205 chip and I am trying to obtain an RSSI reading between two of these modules but the returned reading is always 6 regardless of how far apart the modules are.  I know that these returned values are supposed to correspond to actual signal strength ranges but the returned value is never anything other than '6'.
One module periodically transmits a request to another module which measures the received signal strength of this request. This module then broadcasts its reading. I use a module with the BaseStation app installed to watch the packets being transmitted.
 
When the module receives a request I use this line of code to access the signal strength:
pkt_rssi = (uint8_t)  ( (xe1205_metadata_t*) ((uint8_t*) msg->footer + sizeof(xe1205_footer_t) ) ) ->strength;
And then pkt_rssi gets passed to a sending function.
 
Has anyone had this problem before? How do I get it working correctly?

NesC to C

Hi everyone,

I would like to re-use the OpenMAC which is an open source implementation of the IEEE802.15.4 MAC Layer.
My application layer is coded in C and it runs under a debian system. I use gcc compilation tool chain.
I want to compile OpenMAC for a Linux system and not TinyOS.

So I would like to know if it is possible to adapt the OpenMAC to a linux based implementation?

Does there any way to convert NesC to C code and change "automatically" the TinyOS dependencies of the software (NesC code) to a linux system dependencies. By these dependencies I mean the call of the OS functions.

Sorry, I never used NesC and TinyOS, but I may think about these tools for a standalone implementation of my system. 

Regards 
A.MASSOURI

Help - Micaz - SHT75

Hi EvryOne,
i'm mohammed from morocco, i'm studying embedded systems and i have my graduate project in WSN with TinyOS on Micaz.
about that subject and i just changed few things to let things go with the micaz board.

DATA = MicaBusC.Int3;
SCK  = MicaBusC.PW2;

components HplSensirionSht11P;
HplSensirionSht11P.PWR -> MicaBusC.PW5;  // Power
HplSensirionSht11P.DATA -> MicaBusC.Int3;    //data
HplSensirionSht11P.SCK -> MicaBusC.PW2;       //clk

i've also connected the sht75 to this pins with a pull up resistor for DATA and pull down for the clock.
the code didn't work because waitForResponse() (from HplSensirionSht11C.nc) returns FAIL. and i don't know why ?

 error_t waitForResponse() {
    call DATA.makeInput();
    call DATA.set();
    call CLOCK.set();
    if (call DATA.get()) {

      // the device didn't pull the DATA line low
      // the command wasn't received or acknowledged

      return FAIL;
    }
    call CLOCK.clr();
    return SUCCESS;
  }

i'm asking for your help !
thanks in advance !
best regards !
